Application filed March 27,

To all whom 2 17) (13 Camera:

llc it known that I, lilnrrnnw M, Mnnnrr'r, a citizen of the United States, and a resident of Danvers, county of Essex. Conunonwcalth of Massachusetts, (whose post-office address is .Danvers. Illassaclulsetts.) have. invented an lniprm'en'ient in bhoeLasts of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements in lasts and methods of making the same.

The drawings show one embodiment of a preferred construction of my invention and of a preferred method of making the same.

Figure 1 is a side elevation, partly in sec-- tion' of a last;

Fig. 2 is a section showing a portion of the last connected to a cathode in a preferred manner;

Fig. illustrates diagranimatically the last in process of manufacture by my iinproved method.

In the drawings 1 have shown in Fig. 1 a last 4 preferably formed by the electrolytic deposit of copper or other metal over a form of any suitable material but preferably fusible, so that the last may be made hollow by limiting out the contained material through any suitable aperture typified by the hole 5 drilled through the deposited metal. The copper or other metal forming the principal electrolytic deposit is prefer; ably plated with a. metal which is unaffected oy the fumes incidental to the manucture of rubber shoes and the like. l 7 here the form is of n n1-eoinluctivo material I may coat it with graphite or other pulvcrent eondu-itive. material prior to the electrolytic To provide great strength at the top of the last and also to provide spindle holes for use with the last and a convenient method of connecting the form to the cathode 1 pro-- vide a. metallic reinforcement shaped to conform to the shape of the top of the last and having spindle holes 7 therein. The lat ter may and preferably do project inwardly from the reinforcing element 6 thereby proriding two projections in to the form. W hen the latter is cast the reinforcing strip Specification of Letters Patent.

ductor. -I then introduce into the spindle holes conductor terminals 10 which may be identical with those shown in my co-pending application Serial No. (ll-.607, filed December 3 ltllfi, metal surfaced article. The form is then immersed in any suitable elec trolytic bath 152 and the copper. or other suitable metal electrolytically applied. here copper is used 1 prefer to apply eleetrolyrically a second coating of nickel or other metal not seriously affected by the fu1'nes .incidcntal to the inanut'actm'e of rubber shoes. After the elec olyiir deposit is completed 1 preferably l through the deposit and melt out the material of which the form was composed.

- The metal reinforcing strip 6 especiallywhen provided as hown with projections l3 -l l and spindle holes 7 7. is of marked advantage in any type of last coated with electrolytivaily deposited metal, for it provides a relatively thick top for the last having an extended connection with the deposited metal. a strong cormection between the projections 13 and the form over which the plurality of spindle holes n'opeily pOSlL'l'fiHOLl relative to each other and to the rest of the last.

lVhile l have shown and described a specific last and one method of making the same. it will be understood that changssmay be made in the product and methodwithin the scope of the appended claims.

Claims: 1. t last having a metallic reinforcing" strip at the top thereof and an electrolytically deposited hollow shell, said reinforcing piece providing two inwardly extending projections. and spindle holes extending through said reinforcing;- strip into said projootions.

A i'einforcmnent: For the top of an electrolytically deposited inst inoinding n relativeiy thick strip conforming to the shape of the top of the last and provided with a projection, said strip and said projection Irving upei-tln'ed to provide a spindle hole. 10

In testimony whereof I have signed my name to this specification.
